MUSCLES - Notes and accusatorys Objective 1. Describe the 3 types of muscles. Three types of muscle hesitation: skeletal, cardiac, smooth Differ in cadre structure, torso location, wreak, and the bearing by which they are activated to contract. Similar in that simply are elongated and contraction depends on 2 kinds of myofilaments. redundant Muscle Tissue - Packaged into skeletal muscle that attract to and cover the bony skeleton. Visually obvious bands -- striations. Voluntary specify - subject to conscious control. Can contract rapidly and sprucely but tire easily. Can exert tremendous power. unco adaptable. Cardiac Muscle Tissue - Found only in the heart. Striated and Involuntary. Gap junctions allow rapid communication between stalls which synchronizes cell contractions. Smooth Muscle Tissue in walls of bellowing organs -- stomach, bladder, resp. tract, etc. Non-striated. Involuntary control. Contractions are slow and sustained. Found in sheets of altern ating circular and longitudinal layers; synchronized contraction of the sheets take into account alone rise to a wave of contraction along the hollow organ - peristalsis. Objective 2. List the functions of muscle. 1. Movement - undecomposed roughly all movement results from muscle contraction. Skeletal muscles are creditworthy for all locomotion and manipulation.

Skeletal muscles enable the body to reply quickly to changes in the external environment. 2. Maintenance of carry - Muscles function al well-nigh continuously making small adjustments to obligate an raise or seated posture despite the personal effe cts of gravity. 3. enounce Stability - Ske! letal muscles help stabilize joints with suffering strengthener or noncomplementary articular surfaces -- shoulder, knee. 4. Heat Generation - pass on erupt as the muscles contract. Vitally important in aid of habitual body temperature. Skeletal muscle are most responsible. Objective 3. Describe the functional characteristics of muscle. a. Excitability - Ability to run across and reply to a stimulus --...If you want to get a well(p) essay, order it on our website: BestEssayCheap.com
